Pronóstico: Highest temperature in Wellington on July 28?

Platform comparison

Market context

Polymarket is pricing this Wellington airport temperature contract at **0% YES** today, which means the market is currently assigning no probability to the day’s high landing in the contract’s YES range. Because settlement is based on the highest temperature recorded at Wellington Intl Airport Station on 28 July and paid in USDC through Polygon conditional tokens, the key number is not the city’s general feel but the single daily maximum reported by Wunderground.

That zero reading is easy to understand against Wellington’s July climate profile. Independent forecasts and climate summaries put July daytime highs around **11–12°C**, with nights near **5–6°C**, and show a cool, unsettled winter pattern rather than heat spikes.[1][3][4] BBC Weather currently shows Wellington at **10°C** with steady pressure, which is consistent with a cool late-July setup rather than a move into unusually warm territory.[2] For traders, the current price is therefore a statement about how far the airport temperature would need to overshoot its seasonal norm to hit the target range.

The main catalysts are weather-model revisions, frontal timing, and any brief warm sector crossing the lower North Island before the settlement window closes. On a market like this, the practical watchlist is the airport forecast track, wind direction changes, and whether rainfall arrives early enough to cap the afternoon maximum; those are the factors most likely to move the realised high versus the market’s current 0% stance.[1][3]

Methodology

Methodologically we separate two layers: the live probability (Polymarket mid-price) and the platform attributes (fee, KYC, settlement currency, payment rails). That keeps the comparison honest — a single canonical probability across the row, with the venue-by-venue trade-offs spelt out in the columns next to it.

Resolution & payout

Settlement runs on-chain. Polymarket's contract logic separates YES and NO shares as conditional tokens; at resolution the winning share lifts to $1.00 and the losing one to $0. The outcome input comes from the UMA Optimistic Oracle, which secures against bad resolution with a bond + dispute window.

Once finalised, the smart contract pays USDC to the holders' wallets within minutes — no withdrawal fees beyond Polygon network gas. Kalshi settles in USD via CFTC clearance, Betfair in account currency net of commission, Manifold in play-money mana with no cash-out.

FAQ

Where can I trade this market with the lowest fees?

Polymarket is geo-blocked in the US/UK/EU. The easiest 0%-fee broker into the same order book is Polymarket Qué Es. Kalshi charges up to 7% per trade; Betfair Exchange takes 2-5% commission on net winnings.

What's the difference between YES and NO shares?

A YES share pays $1.00 if the event happens, $0 otherwise. A NO share pays $1.00 if the event doesn't happen. The market price between 0¢ and 100¢ is the implied probability.

How fast are USDC deposits?

Polygon credits deposits after 12 confirmations — usually under 30 seconds. Withdrawals follow the same path and land back in your wallet within minutes.

Do I need to KYC for this market?

On Polymarket directly, no — it's wallet-based. Intermediary brokers like Polymarket Qué Es trigger KYC only above $1,500 of lifetime trading volume; under that you trade pseudonymously with a single wallet address.

How reliable are the quoted odds?

The YES/NO percentages are the live mid-prices of the Polymarket order book. On deep markets they move every few seconds; on thinner ones you'll see short plateaus.
